I am trying to study the electron transfer (ET) between charge-localized states on first and last carbon atoms in a C8H18 chain. To obtain the charge localized states I use CDFT. I'm using version 6.6, so the combination of CDFT and ET works. I first find the localized stated on the first (atom no. 1) and the last carbon atom (atom no. 21), and then feed the corresponding vectors back to the ET module. However, I get very large coupling energy V(RP). Here is the input file I use:
